When Everykey is close to your phone, laptop, tablet, house door, car door, bike lock, or another access-controlled device, it unlocks that device and then re-locks it when you're out of range so your device is safe and secure when it's out of your trusted hands. Everykey can also automatically log you into your website accounts, like your email and social media. If you lose your Everykey, you can remotely freeze it, so no one else can use it.
